Since my most recent Windows 10 update to version 21H1 with I cannot open the Context Menu (right click) on the Windows 10 Taskbar apps.
This is specifically on the apps themselves and not the Task Tray, Start Menu, Cortana, Search or Task View -- all these worked correctly.
Just like some other questions, as some of the comments addressed on these, their workarounds (such as restarting explorer, restarting the tile service) and answers (such as fixing Local Group Policy for context menu permissions on the Taskbar) did not fix the issue. This also displays no errors at all.
